planting tiny grape hyacinth bulbs

We just dug up a bed of grape hyacinths that have not been touched for about 15 years, perhaps more. We have hundreds of tiny bulbs along with the big ones, and they all have a tiny green leaf attached. Can I use the tiny, smaller than a pea, ones and, if so, how deep to bury them? Unfortunately, we did not do this earlier in the season and are now racing to get them in before the temps plummet on Tuesday.
